What computer do you have? Is it a laptop or a desktop? Have tried to contact the computer manufacturer: Computer Manufacturer Support Websites first and see if they have any solution availble since the wireless adapter is native to this system? check with them first and then let us know so we can move on into the next step.
What did your OEM say abaout it?
Did you try to clean uninstall the drivers and then try the drivers from the OEM? Should you experience the same issue after a clean uninstall and then re-installing again you may try the following:
Download and save the drivers for the Intel® Centrino® Advanced-N 6205 according to your OS: Drivers & Software
1. Go to Control Panel, Programs and Features and Uninstall "Intel® PROSet/Wireless Software", if it is installed. When prompted, choose the option to "Discard settings".
2. In Control Panel, Device Manager, Network Adapters, right click on the Intel® Centrino® Advanced-N 6205 and Uninstall it. Make sure you mark the option to "Delete the driver software for this device".
3. Reboot the PC or scan for hardware changes, check device manager and if an older driver is detected and installed, repeat the actions to uninstall and delete it as well. Repeat this process until the OS does not allow deleting the driver, or until the controller shows as Unknown Device.
4. Reboot or scan for hardware changes, then uninstall and delete any older driver versions as you did for the Wireless adapter.
5. Install the Intel® Wireless driver. During the first steps of PROSet/Wireless installation, make sure to customize the installation and install all the 3 driver components.
Also having the same problem same card as well Centrino Adv-N 6205 on win7. going to try your suggestions will post back on results also. Also not sure if this is relative but you have adv-N drivers posted in 2016 but intel autodetect keeps on telling me a version from over a year ago is the newest one. when clearly... Download Intel® PROSet/Wireless Software and Drivers for Windows 7* shows otherwise.... so which should we be using?
addendum: Also no OEM software for me this is a add-on PCI-E card Product code: 62205ANHMWDTX1. followed your steps found apparently several drivers installed had to re-scan for HW changes several times and removed drivers twice to get to the 'unknown hardware' step. Installed latest by Intel's driver page will keep updated as to if this solves the issue for myself.
well after a week without issues.... blammo BSOD out of nowhere..
